Attach "Post-It" notes to .PDF files

[Peter Hugosson-Miller <hugge@netg.se>]

In Acrobat Exchange for Windoze, there is the capability to add small 
yellow "Post-It" notes to annotate the document you are reading. This is 
a very useful way to review and correct almost finished documents 
without changing any of the original content.

Does anyone know of a way to achieve the same functionality in Linux? I 
have downloaded the free Linux Acrobat reader from Adobe, but it's not 
in there (or at least I cant find it).

Thanks in advance,
